Answer 2

Answer:

700 sq-m

Step-by-step explanation:

To find the area of rectangular garden.

given that:

Perimeter of rectangular park= 160 m

Breadth = 10 m

To find:

1) Length

2) Area

We know that

Perimeter of rectangle = 2(l+b) unit

$2(l + b) = 160 \\ \\ l + b = \frac{160}{2} \\ \\ l + 10 = 80 \\ \\ l = 80 - 10 \\ \\ l = 70 \: m$

Area:

$= l \times b \\ \\ = 70 \times 10 \\ \\ = 700 \: {m}^{2}$

Hope it helps you.
