Question

Area of rectangular garden 40 m long is 1,120 sq. m. Find the width of the rectangle

plz help

Answer 1

Answer:

$\huge\colorbox{yellow}{Given\:-}$

Length of garden = 40 m

Area of garden = 1120 sq m

$\huge\colorbox{yellow}{To\:Find\:-}$

The width of the garden

$\huge\colorbox{yellow}{Solution\:-}$

$\small\underbrace\mathrm\red{Using\:formula}$

$\boxed{Area\:of\:rectangle\:=\:Length \times breadth}$

Let width be x

Now, ATQ.

$1120 = 40 \times x$

$\frac{1120}{40} = x$

$28 = x$

$\pink{ = > x = 28 \: m}$

Hence, the width of the rectangular garden is 28 m

Answer 2

Step-by-step explanation:

Length AB = 40 m and breadth BC = 25 m

∴ Area of lawn ABCD = 40 m x 25 m = 1000 m2

Length PQ = (40 + 2 + 2 ) m = 44 m

Breadth QR = ( 25 + 2 + 2 ) m = 29 m

∴ Area of PQRS = 44 m x 29 m = 1276 m2

Now,

Area of the path = Area of PQRS − Area of the lawn ABCD

= 1276 m2 − 1000 m2

= 276 m2

Rate of levelling the path = Rs. 8.25 per m2

∴ Cost of levelling the path = Rs. ( 8.25 x 276)

= Rs. 2277..
