Answer 1

Answer:

Step-by-step explanation:

(a)Here the rectangle and the square has the same perimeter of 40m.

Perimeter of a square = 4(side length)

40= 4(side)

Hence side length of square is 10 m

Now the diagonal of square is equal to √2 times its side.(d= diagonal)(s=side)

i.e d=s√2

=10√2 = 14.14...

Hence the diagonal is equal to 10√2 or 14.14...

(b) Here is , breadth (B) = and Length (L) of the rectangle.

It is given that B=L-4 (in question)

Now, Perimeter of a rectangle =2(L+B)

40= 2(L+B)

L+B= 20

L+(L-4)= 20 .... Substitute B=L-4

2L-4=20

2L=24

L=12

L+B=20

12+B=20... Substitute L=12

Hence B=8

Therefore

The length of the rectangle is 12 m and breadth is 8 m
