Question

C) The area of a rectangle is 80 cm² and it is 8 m broad.In process

Answer 1

Answer:

i) the length is 10cm

ii) the perimeter is 36 cm

Step-by-step explanation:

i) We know that Area of a rectangle can be found by using the following formula...

A = l x w

(where A is area of the triangle, l is the length of the triangle, and w is the width of the rectangle).

From this we know that

l = A/w

$l = 80cm^{2} / 8cm = 10cm$

ii) Now that we know both the length and the width we know we can find the perimeter by using the following formula...

P = 2(l + w)

$P = 2(10cm+ 8cm )\\P = 20cm + 16cm\\P = 36cm$
