Answer 1

Answer:

7. 6.8m²

8. 74 cm

9. ₹1400

Step-by-step explanation:

7) Perimeter of table top (rectangle) =2(l+b)

=2(2.15+1.25)

=2(3.4)

=6.8m²

8) Length of wooden frame needed to frame photograph = perimeter of photograph

Perimeter = 2(l+b)

=2(25+12)

=2(37)

=74 cm

9) Fence perimeter (square) = 4(side)

=4(175)

=700m

Rate=₹20/m

Cost=700×20

=₹1400
