Question

FIND THE COST OF FENCING A RECTANGULAR FIELD 34 M LONG AND 18 M WIDE AT 2.25 PER METRE

Answer 1

peri = 2(l + b)
= 2( 34 + 18)
=2 × 52
=104 m
If Rate of fencing 1 m = Rs. 2.25
Therefore, for 104 m = Rs. 2.25 x 104 = Rs.234.

Answer 2

Given - Length, width and cost

Find - Cost of fencing

Solution - Perimeter of rectangular field = 2(length + breadth)

Perimeter of rectangular field = 2(34 + 18)

Performing addition

Perimeter = 2*52

Performing multiplication

Perimeter = 104 m

Cost of fencing 1 metre = 2.25

Cost of fencing 104 m = 2.25*104

Performing multiplication

Cost of fencing rectangular field = 234

Hence, the cost of fencing the rectangular garden is 234.
