Question

Find the perimeter and area of a rectangle of:

(b) L = 14.5 km, B = 7 km
(a) L = 16.5 cm, B = 12 cm
(c) L = 21 cm, B = 13.7 cm​

Answer 1

Answer:

b. perimeter = sum of all sides.

so. 14.5 + 7 km = 21.5

area of triangle = length×breadth

so. 14.5 × 7= 101.5 km

a. perimeter= 16.5 + 12 = 28.5cm

area= 16.5 × 12 =198cm2

c. perimeter = 21 + 13.7 = 34.7cm

area = 21× 13.7=287.7cm2
