Question

Find the area of the composite figure
10 ft
4 ft
3 ft
6 ft
square feet

Answer 1

61 square feet

Explanation:

Your rectangle has a area of A = w l

A = 4*10 = 40

The triangle has a area of A = h (b/2)

A = 7 (6/2)

A = 21

Add both for the area

Answer 2

Exercise Problem Solution

1 Find the perimeter of a triangle the sides of which are 10 in, 14 in and 15 in. P = 10 in + 14 in + 15 in = 39 in

2 A rectangle has a length of 12 cm and a width of 4 cm. Find its perimeter. P = 12 cm + 12 cm + 4 cm + 4 cm = 32 cm

3 Find the perimeter of a regular hexagon with each side measuring 8 m. P = 6(8 m) = 48 m

4 The perimeter of a square is 20 ft. How long is one side? 20 ft ÷ 4 = 5 ft

5 The perimeter of a regular pentagon is 100 cm. How long is one side? 100 cm ÷ 5 = 20 cm
