Question

Find the length of a rectangular park whose area is 672 m2 and breadth is 21 m​

Answer 1

Answer:

A= 672 m²

l × b = 672 m²

l × 21 = 672 m²

21l=672 m²

l = 672÷21

l = 32

Answer 2

Step-by-step explanation:

$area \: of \: rectangular \: park \: = l \times b \\ 672 \: {m}^{2} = \: l \times 21 \\ \frac{672}{21} \: m = l \: \\ l = 32 \: m$
