(b) The lid of a square box of side 50 cm is sealed all round with tape. Find the length of
the tape required.
​

Answer 1

Answer:

a) perimeter of a rectangle is 2 (l + b)

dimensions of the table top = 2m 15cm by 1m 65cm

= 2(2.15+1.65)

= 2(3.8)

= 7.6cm

b)  Square has 12 Edges.

Each edge need 50cm tape.

Multiply 12×50= 600cm

Answer 2

perimeter of a rectangle is 2(l +b)

2m 15 cm by 1m 65cm

so here,

2(2.15+1.65)

2(3.8)

= 7.6 = 7 m 60 cm
