Question

Find the cost of fencing a rectangular field of length 50m and breadth 42m at the rate ₹8 per m.

Answer 1

ANSWER:

• Cost of fencing the rectangular field = ₹1472

GIVEN:

• Length of rectangle = 50 m
• Breadth of rectangle = 42 m

TO FIND:

• Cost of fencing the rectangular field.

SOLUTION:

Perimeter of rectangle = 2(length+Breadth)

Length of rectangle= 50 m

Breadth of rectangle = 42 m

=> Perimeter of rectangle = 2(50+42)

=> Perimeter of rectangle = 2(92)

=> Perimeter of rectangle = 184 m

Cost of fencing rectangular field per meter = ₹8

Cost of fencing rectangular field of 184 m = ₹8(184)

=> Total cost = ₹1472

NOTE:

Some important formulas:

Area of Square = (Side)²

Area of rectangle = Length*Breadth

Area of rhombus = Base*Altitude

Area of parallelogram = Base*Altitude

Area of Triangle = (Base*Altitude)/2

Perimeter of Square = 4(side)

Perimeter of rectangle = 2(length+breadth)

Answer 2

Answer:

a fencing a rectangular 2(l+b)

so according to question

2(50+42)

2*92=
