if area of rectangle is120/49cmsq and one of its sides is10/7cm,find the length of other side.
area of rectangle ÷ one side = the other side, so ....
(120/49) ÷ (10/7) = ....
We already know that area of a rectangle= length× breadth
~area is given= 120/49cm²
~ side( length) is given= 10/7cm
>other side ( breadth)= area/ length
~>> 120/49cm² ÷ 10/7 cm
= 12/7cm ( ans)
The answer is 44/7.
To find the length of the other side of the rectangle, we can use the formula for the area of a rectangle:
Area of rectangle = Length × Width
Given that the area of the rectangle is 120/49 cm² and one side is 10/7 cm, we can substitute these values into the formula:
120/49 = Length × (10/7)
To find the length, we need to isolate it. Start by multiplying both sides of the equation by 49/10 to get rid of the fraction:
(120/49) × (49/10) = Length × (10/7) × (49/10)
Simplifying:
120/10 = Length × (49/7)
Now, divide both sides of the equation by 49/7 to solve for the length:
(120/10) ÷ (49/7) = Length × ((49/7) ÷ (49/7))
Simplifying again:
12 = Length × 1
Therefore, the length of the other side of the rectangle is 12 cm.
