Question

two squares of a side 2cm are cut out of a rectangle 10cm by 5cm . Find the perimeter of the remaining figure​

Answer 1

Answer:

22

Step-by-step explanation:

perimeter of rectangle = 2(l+b)

2(l+b) =2(10+5)

=2(10+5) =2(15) or 2×15

=2(10+5) =2(15) or 2×15 =30cm

two square of side two:-

we have to find area of squares because we have to remove it from rectangle of perimeter 30cm. side of square is 2cm

Area of square = side×side

= 2×2

2×2 = 4cm sq.

unit of area is always written in M sq. or Cm sq.

there are given 2 squares =2×4=8cm sq.

we have to find perimeter of remaining fig. of rectangle = perimeter of rectangle-Area of square

=30-8

=22cm
