Question

The length and width of a rectangle garden are 7 km and (x - 8) km respectively. What will be the
breadth of a garden , if the area of the garden is 42 km^2

Answer 1

Answer:

Length=7km.

Width=(x-8) km.

Area of garden=42km²

Area of rectangle=Length× Breadth

42=7×(x-8)

$\frac{42}{7} = x - 8$

$6 = x - 8$

$6 + 8 = x$

$14 = x$

Width of the rectangle park =(x-8) km=14-8=6km

Breadth =6 km

Answer 2

Answer:

Width would be 6 km

Step-by-step explanation:

Since, the area of a rectangle,

$A=l\times w$

Where,

l = length,

w = width,

Here, l = 7 km, w = (x-8) km,

Thus, the area of the rectangle,

$A=7(x-8)$

According to the question,

A = 42 km²,

7(x-8) = 42

x - 8 = 6

Hence, the width of the rectangle = x - 8 = 6 km
