Question

If the radioif the radio of the length to the breath of a rectangle is 1:1 what kind of a rectangle is it of the lenghth to the breath of a rectangle is 1:1 what kind of a rectangle is it

Answer 1

Answer:

Step-by-step explanation:

1. Find the length of a rectangle whose breadth is 5 cm and area is 90 sq. cm.

Solution:

Breadth (b) = 5 cm,

Area (A) = 90 sq. cm.

Length (ℓ) = Area ÷ breadth

= 90 ÷ 5

= 18

Therefore, length of rectangle = 18 cm.

2. Find the breadth of a rectangle whose length is 200 cm and area is 10 m2.

Solution:

Length (l) = 200 cm,

Area (A) = 10 m2

100 cm = 1 m.

Length (ℓ) = Area ÷ breadth

Length (ℓ) = 200/100 m = 2 m.

Breadth (b) = A ÷ ℓ

= 10 ÷ 2 m.

= 5 m.

Therefore, breadth of rectangle = 5 m.
