Question

the area of the rectangular lawn is 1350sq m. if its length is 15m. find its breadth also find its perimeter.​

Answer 1

Solution

Given :-

• the area of the rectangular lawn = 1350 m²
• Length = 15 m

Find :-

• Breadth of Rectangular lawn
• Perimeter of the rectangular lawn

Explanation

Using Formula

★Area of rectangle = ( Length × Breadth )

★Perimeter of rectangle = 2 × (Length + Breadth )

So,

==> Area of rectangular lawn = 1350

==> 15 × Breadth = 1350

==> Breadth = 1350/15

==> Breadth = 90 m

Now, Calculate perimeter

==> Perimeter of rectangular lawn = 2 × ( Length + Breadth)

Keep Value,

==> Perimeter of rectangular lawn = 2 × (15 + 90)

==> Perimeter of rectangular lawn = 2 × 105

==> Perimeter of rectangular lawn = 210 m

Hence

• Breadth of Rectangular lawn = 90 m
• Perimeter of rectangular lawn = 210 m

Answer 2

Step-by-step explanation:

Area of lawn =1350sqm

length X breadth =1350

15mXBreadth=1350

Breadth =(1350/15)m

=1350/15

=90m

perimeter =2(l+b)=2*(15+90)=210m
