Question

The length and diagnostic of rectangle is 58 cm 79 cm find its breath and perimeter

Answer 1

I will presume that by "diagnostic", you mean diagonals.

Given: length= 58 cm

diagonal= 79 cm

We know that,

(breadth)²+(length)²= (diagonal)² (∵Pythagorean Theorem)

=(breadth)²+(58)²=(79)²

=(breadth)²+3364=6241

=(breadth)²=6241-3364

=(breadth)²=2877

thus, breadth= √2877=53.6 cm

perimeter= 2(length+breadth)= 2(53.6+58)=223.2 cm

∴The breadth is 53.6 cm and the perimeter is 223.2 cm.

Hope this helps!
