Question

Today's maths homework
1.Find the area and perimeter of the following rectangles
i)Length = 13 cm , Breadth = 9 cm
ii)Length = 15 cm , Breadth = 7 cm
iii)Length = 18 cm , Breadth = 11 cm
iv)Length = 5.4 cm , Breadth = 2.2cm
v)Length = 6.5 cm , Breadth = 3.5 cm.
I need immediately correct answer for this question.

Answer 1

Step-by-step explanation:

1) perimeter:- 2×(l+b)

2 × 13 + 9

2×22

=44

Area :- l×b

13×9

117

2) Perimeter:-2×(l+b)

2×15 + 7

2×22

= 44

Area :- l×b

15×7

105

3) Perimeter:- 2×(l+b)

= 2×18+11

= 2×29

= 58

Area:- l×b

= 18 × 11

= 198

4) Perimeter:- 2×(l+b)

= 2×5.4+2.2

= 2×7.6

= 15.2

Area :- l×b

= 5.4×2.2

=11.88

5) Perimeter:- 2×(l+b)

= 2×6.5+3.5

= 2× 10

= 20 cm

Area:- l×b

=6.5×3.5

= 22.75
