Question

6th sum urgently please no direct answers

Answer 1

By the Pythagorean theorem, we get,

√(10^2-8^2) = 6

So, the width of the rectangle is 6 m.

Thus, perimeter = (8+6+8+6) m = 28 m.

Answer 2

Using Pythagoras theorem BC²=AC²-AB²
BC² =100-64
BC=6


breath=6cm
length=8cm

Perimeter=2(l+b)
=2(8+6)
=2(14)
=28cm
