Question

In the figure below, the inner rectangle is drawn within 1 cm from the outer rectangle. If the perimeter of the outer rectangle is 26 cm, what will be the perimeter of the inner rectangle? *

1️⃣ 24 cm
2️⃣ 22 cm
3️⃣ 20 cm
4️⃣ 18 cm

Answer 1

Answer:

22cm

Step-by-step explanation:

now formula of perimeter = 2(l+b)

2(l+b) = 26cm (outer)

(l+b) = 13 cm

now for inner there is 1cm gap so take out 2 cm bcause 1 cm taken out frm length and one frm breadth

then 11+11 = 22cm
