Question

A rectangle has its length 4 metre and breadth 3 metre find its perimeter and area and its diagonal​

Answer 1

Answer:

perimeter=2(l+b)

2(4+3)

2(7)

14m

area:

lxb

4x3

12m

Answer 2

Perimeter = 2(l+b)

=2(4+3)

=2×7

= 14m

Area = l×b

=4×3

=12m²

For diagonal we will use pythagoras theorem,

Diagonal² = side1² + side2²

= 4² + 3²

=16+9

=25

25½

=5

hence diagonal = 5m
