Question

the cost of levelling a rectangular garden at ₹3.50 per sq m .if the its length is 26m and breadth is 20m.

Answer 1

Answer:

200m

Step-by-step explanation:

l=3x

b=2x

cst f levelling = l ×b × 3.50

8400= 3x × 2x × 3.50

8400= 6 × 3.50 × x²

x² =8400 ÷ 21

x² = 400

x= 20

l = 3 × 20 =60

b = 2× 20 = 40

perimeter =2(l+b)

=2(60+40)

=2 × 100

=200 m
