I don't know diagonal

Answer 2

Answer:

perimeter= 94 cm.

Area= 420 cm².

Diagonal= 37 cm.

Step-by-step explanation:

1) Perimeter of Rectangle= 2*(L+B)

= 2*(35+12)

= 2*47

= 94.

Perimeter of Rectangle= 94 cm.

2) Area of Rectangle= L*B

= 35*12

= 420.

Area of Rectangle= 420 cm².

3) Diagonal of Rectangle

According to Pythagoras,

diagonal²= Length ²+ Width ²

= ✓(35²+12²)

= 37.

Diagonal of Rectangle= 37 cm.
