Question

Area of a rectangle is 80 square cm and length is 10 cm. Find its breadth and perimeter.

Answer 1

Answer:

breadth = 8cm

perimeter = 36cm

Step-by-step explanation:

length = 10cm

area = 80 sq. cm

∴ $breadth = \frac{area}{length}$

= (80/10)cm = 8cm

∴ $perimeter = 2(l + b)$

= 2(10 + 8)cm

= (2 × 18)cm = 36cm
