Figure EFGH is made up of six identical rectangles. Each rectangle has a length of 16 cm.
- Find the perimeter of Figure EFGH.
- Find the area of Figure EFGH
(a)
Breadth of one rectangle = 1 u
Length of one length = 2 u
2 u = 16
1 u = 16 ÷ 2 = 8
Length of Figure EFGH = 4 u
Breadth of Figure EFGH = 3 u
Perimeter of Figure EFGH
= 4 u + 4 u + 3 u + 3 u
= 14 u
= 14 x 8
= 112 cm
(b)
Area of 1 rectangle
= 16 x 8
= 128 cm
2 Area of Figure EFGH
= 6 x 128
= 768 cm
2 Answer(s): (a) 112 cm; (b) 768 cm
