Figure MNPQ is made up of six identical rectangles. Each rectangle has a length of 14 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 = 14
1 u = 14 ÷ 2 = 7
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 7
= 98 cm
(b)
Area of 1 rectangle
= 14 x 7
= 98 cm
2 Area of Figure MNPQ
= 6 x 98
= 588 cm
2 Answer(s): (a) 98 cm; (b) 588 cm
