Question

the diagonal of a square is 5 root 2m. find the area and perimeter
​

Answer 1

Answer:

Step-by-step explanation:

Diagonal =5√2 m

Let side of square be X m

Using Pythagoras theorem

x²+x²= (5√2)²

2x²=2*25

X² = 25

X =√25

X=5 metre

Now find perimeter and area yourself

Answer 2

Answer:

Step-by-step explanation:

LET THE SIDE OF THE SQUARE BE A

DIAGONAL OF THE SQUARE = √2*A

GIVEN ;

5 √2 = √2 A

A = 5 M

AREA OF THE SQUARE = A²

                                        = 5²

                                        = 25 M²

PERIMETER OF THE SQUARE = 4*A

                                                  = 4*5

                                                  = 20 M.

THEREFORE:

AREA OF THE SQUARE = 25 M²

PERIMETER OF THE SQUARE = 20 M.
