Figure TUVW is made up of ten identical rectangles. Each rectangle has a length of 24 cm.
- Find the perimeter of Figure TUVW.
- Find the area of Figure TUVW
(a)
Breadth of one rectangle = 1 u
Length of one length = 4 u
4 u = 24
1 u = 24 ÷ 4 = 6
Length of Figure TUVW = 8 u
Breadth of Figure TUVW = 5 u
Perimeter of Figure TUVW
= 8 u + 8 u + 5 u + 5 u
= 26 u
= 26 x 6
= 156 cm
(b)
Area of 1 rectangle
= 24 x 6
= 144 cm
2 Area of Figure TUVW
= 10 x 144
= 1440 cm
2 Answer(s): (a) 156 cm; (b) 1440 cm
