1
Find the side of a Triangle whose perimeter is 28 in
9 in10 in9 in
Perimeter = 28 in
Solution
Perimeter = Sum of the measure of all the sides.
Perimeter = side1 + side2 + side3.
Perimeter = 28 in
side2 = 9 in
side3 = 9 in
To find side3,
side1 = Perimeter - (side2 + side3)
side1 = 28 - (9 + 9)
∴ side1 = 10 in
2
Find the side of a Parallelogram whose perimeter is 18 in
6 in3 in6 in3 in
Perimeter = 18 in
Solution
Perimeter = Sum of the measure of all the sides.
Perimeter = side1 + side2 + side3 + side4.
Perimeter = 18 in
side1 = 6 in
side2 = 3 in
side4 = 3 in
To find side3,
side3 = Perimeter - (side1 + side2 + side4)
side3 = 18 - (6 + 3 + 3)
∴ side3 = 6 in
3
Find the side of a Pentagon whose perimeter is 15 in
3 in
Perimeter = 15 in
Solution
pentagon has 5 sides,and all side have equal length
Perimeter = 5 x side
To find side,
side =
Perimeter5
Perimeter = 15 in
side =
155
∴ = 3 in
4
Find the side of a Rectangle whose area is 45 in2
9 in5 in
Area = 45 in2
Solution
To find length,
Area = 45 in 2
Breadth (b) = 5 in
Area = l x b
l =
Areab
Length (l) =
455
∴ Length (l) = 9 in
5
Find the side of a Square whose area is 100 in2
10 in
Area = 100 in2
Solution
To find side,
Area = 100 in 2
Area = side2
side = √area
side = √100
∴ side = 10 in
6
Find the side of a Square whose area is 49 in2
7 in
Area = 49 in2
Solution
To find side,
Area = 49 in 2
Area = side2
side = √area
side = √49
∴ side = 7 in
7
Find the side of a Rectangle whose area is 60 in2
10 in6 in
Area = 60 in2
Solution
To find breadth,
Area = 60 in 2
Length (l) = 10 in
Area = l x b
b =
Areal
Breadth (b) =
6010
∴ Breadth (b) = 6 in
8
Find the side of a Trapezoid whose perimeter is 18 in
3 in2 in3 in10 in
Perimeter = 18 in
Solution
Perimeter = Sum of the measure of all the sides.
Perimeter = side1 + side2 + side3 + side4.
Perimeter = 18 in
side1 = 3 in
side3 = 10 in
side4 = 2 in
To find side4,
side2 = Perimeter - (side1 + side3 + side4)
side2 = 18 - (3 + 2 + 10)
∴ side2 = 3 in
9
Find the Radius of a Circle whose area is 37.68 in2
6 in
Perimeter = 37.68 in
Solution
To find radius,
Perimeter = 37.68 in
Perimeter = 2 x π x r
Radius (r) =
Perimeter2 x π
Radius (r) =
37.682 x 3.14
; where π = 3.14
∴ Radius(r) = 6 in
10
Find the Radius of a Circle whose area is 43.96 in2
7 in
Perimeter = 43.96 in
Solution
To find radius,
Perimeter = 43.96 in
Perimeter = 2 x π x r
Radius (r) =
Perimeter2 x π
Radius (r) =
43.962 x 3.14
; where π = 3.14
∴ Radius(r) = 7 in
