Figure STUV is made up of six identical rectangles. Each rectangle has a length of 12 cm.
- Find the perimeter of Figure STUV.
- Find the area of Figure STUV
(a)
Breadth of one rectangle = 1 u
Length of one length = 2 u
2 u = 12
1 u = 12 ÷ 2 = 6
Length of Figure STUV = 4 u
Breadth of Figure STUV = 3 u
Perimeter of Figure STUV
= 4 u + 4 u + 3 u + 3 u
= 14 u
= 14 x 6
= 84 cm
(b)
Area of 1 rectangle
= 12 x 6
= 72 cm
2 Area of Figure STUV
= 6 x 72
= 432 cm
2 Answer(s): (a) 84 cm; (b) 432 cm
