Question

A rectangle and a square have the same area. the side of the square have some area. the side of the square is 400 cm and the breath of the rectangle is 125cm. Find the length of the rectangle ​

Answer 1

Answer:

1280 cm

Step-by-step explanation:

Side of square = 400 cm

Breadth of rectangle = 125 cm

Area of square = Area of rectangle

(400)² = l * 125

160000/125 = length

length = 1280 cm

Answer 2

Answer:

first we need to take out surface area of square after which we can equate it with the formula of surface area of rectangle

Since we have breadth of rectangle then therefore we can let the value of of length be x

Step-by-step explanation:

Given-

• side of square (400 CM)
• breath of rectangle (125cm)
• area of square is equal to area of rectangle

Find-

• the length of rectangle

Proof-

Surface Area of square - Side X Side

400 x 400

=1,60,000

since area is equal than

Surface Area of rectangle - length X breadth

160000 = X X 125

160000 = X

---------------

125

1280 = X

X was tha length of the rectangle
