Question

QUIZ 1. Dimensions of a rectangular frame are 40 cm and 10 cm and dimension of a square frame is 25 cm. Both the frames are to be decorated with a border at the rate of ₹3 per cm. Which border will cost more ?​

Answer 1

Step-by-step explanation:

Rectangular Frame

Length = 40cm

Breadth = 10cm

Perimeter = 2(l+b)

= 2(40+10)

= 2(50)

= 100cm

Rate of the border = ₹3 per cm

Therefore, rate of the border of the rectangular frame = 3 x 100

= ₹300

Square Frame

Side = 25cm

Perimeter = 4(s)

= 4(25)

= 100cm

Rate of the border = ₹3 per cm

Therefore, rate of the border of the square frame = 3 x 100

= ₹300

Therefore, both the frames will cost the same for decorating the border.
