Figure MNPQ is made up of six identical rectangles. Each rectangle has a length of 8 cm.
- Find the perimeter of Figure MNPQ.
- Find the area of Figure MNPQ
(a)
Breadth of one rectangle = 1 u
Length of one length = 2 u
2 u = 8
1 u = 8 ÷ 2 = 4
Length of Figure MNPQ = 4 u
Breadth of Figure MNPQ = 3 u
Perimeter of Figure MNPQ
= 4 u + 4 u + 3 u + 3 u
= 14 u
= 14 x 4
= 56 cm
(b)
Area of 1 rectangle
= 8 x 4
= 32 cm
2 Area of Figure MNPQ
= 6 x 32
= 192 cm
2 Answer(s): (a) 56 cm; (b) 192 cm
