Question

What is length of the wooden strip required to frame a photograph of length and breadth 30 cm and 20cm respectively​

Answer 1

Answer:

100 cm of wooden strip is required to frame the photograph

Step-by-step explanation:

• length = 30 cm
• breadth = 20 cm

FORMULA

PERIMETER OF RECTANGLE = 2 ( L+ B )

PERIMETER = 2 (30 +20)

= 2 × 50

= 100 CM

Answer 2

Answer:

100cm

Step-by-step explanation:

Given

l =30 cm

b=20 cm

perimeter = 2(l+b)

= 2(30cm+ 20cm)

= 2×50cm

= 100cm

Since, perimeter of photograph = length of wooden strip

Therefore, length of wooden strip required =100cm
