PLS. ANSWER IT.. IT URGENT.​

Answer 1

Step-by-step explanation:

perimeter of rectangle is 2 (l+b )

2 (l +60 ) =540

l +60 =270

l =210cm

Answer 2

Question:

Q) Find the length of the rectangle whose perimeter is 540 cm and breadth is 60cm

Answer:

A.T.Q

Perimeter of the rectangle is 540cm.

Breadth of the rectangle is 60cm.

we know:

Perimeter of rectangle =2×(length+breadth)

So,

540cm=2×(length+60cm)

=> length=$\frac{540-(60×2)}{2}$

=> length =210cm

Now let's check:

Now, length = 210cm

and, breadth = 60cm

therefore:

Perimeter = 2(210+60)cm

=2×270cm

=540

Hence the length is equal to 210cm.
