Question

from a rectangular sheet of tin of size 100cm by 80cm are cut four squares of side 10cm from each corner find the area of the remaining sheet

Answer 1

given,
length=100cm
breadth=80cm
side of square=10cm
no. of square cut=4

area of rect. = l × b
= 100 ×80
=8000 cm sq.


area of square = 10 × 10
= 100 cm sq.
for 4 squares = 4×100
=400 cm sq.

area of remaining sheet = area of rect. - area of square
= (8000 - 400) cm sq.
= 7600 cm sq.

Hence, the area of remaining sheet is 7600 cm sq.

Step-by-step explanation:

PLEASE ADD ME AS BRAINLY

Step-by-step explanation:

Given,

length=100cm

breadth=80cm

side of square=10cm

no. of square cut=4

area of rect. = l × b

= 100 ×80

=8000 cm sq.

area of square = 10 × 10

= 100 cm sq.

for 4 squares = 4×100

=400 cm sq.

area of remaining sheet = area of rect. - area of square

= (8000 - 400) cm sq.

= 7600 cm sq.

Hence, the area of remaining sheet is 7600 cm sq
