Question

The breadth of a rectangular field is 75% of its length. If perimeter of the field is 1050 m, what will be th 2 of field ?
A) 65700 sq.m
B) 54500 sq.m
C) 78700 sq.m
D) 67500 sq.m

Answer 1

Hey mate ^_^

Answer:
=======

Let the length be 'x' and breadth be 'y'.

$y = x × \frac{3}{4} ---- (1)$

$2(x+y) = 1050$

$2x + 2y = 1050$

$x+y = 525 ---- (2)$

From equations $(1) and (2),$

We get,

$x = 300m, y = 225 m$

$Area = x × y$

$Area = 300 × 225$

$Area = 67500 sq.m.$

Therefore,

Correct option D) 67500 sq.m.

Let the length be 'x' and breadth be 'y'.

y = x × \frac{3}{4} ---- (1)




since

2(x+y) = 1050




hence,

x+y = 525 ---- (2)

From equations (1) and (2)

We get, 

x = 300m,

y = 225 m

Area = length*breadth

Area = 300 × 225

Area = 67500 m^2
