Question

the area of a hall is 1620 metre square the breadth of the hall is 36 metre long find the length of the hall. also find the perimeter of the hall.​

Answer 1

Answer:

Area of rectangle = length.breadth = 1620m²

Breadth given is 36m

LB =1620

L=1620/36

Length =45m

Perimeter = 2(l+b)

2(45+36)

2×81

Perimeter = 162m

Answer 2

Area of the garden=98 m square

length of the garden= 14m

therefore breadth of the garden= A/L = 1620÷ 36

=45m

perimeter of a rectangle= 2(l+b)

2(45+36)

2× 18 = 162 m perimeter of a hall
