Question

Find the length of a rectangle plot of land if its area is 700m² and its breadth is 20 m. Also find its perimeter​

Answer 1

Answer:

Length = 35m

Perimeter = 110m

Explanation:

length = area/breadth

= (700/20)m = 35m

Perimeter = 2(l + b) = 2(35 + 20)m = (2 × 55)m

= 110m

Answer 2

Given:

A rectangle plot with

• Area = 700 m²
• Breadth = 20 m

What To Find:

We have to find the length and perimeter of the rectangle plot.

How To Find:

To find the length and perimeter we will use,

• Area = Length × Breadth
• Perimeter = 2(Length + Breadth)

Solution:

• Finding the length

Using the formula,

⇒ Area = Length × Breadth

Substitute the values,

⇒ 700 m² = Length × 20 m

Take 20 to LHS,

⇒ $\sf{\dfrac{700}{20} = Length}$

Divide 700 by 20,

⇒ 35 m = Length

∴ Thus, the length of rectangle plot is 35 m.

• Finding the perimeter

Using the fomula,

⇒ Perimeter = 2(Length + Breadth)

Substitute the values,

⇒ Perimeter = 2(35 + 20)

Solve the brackets,

⇒ Perimeter = 2 × 55

Multiply 2 by 55,

⇒ Perimeter = 110 m

∴ Thus, the perimeter of rectangle is 110 m.
