it should be scalene

Step-by-step explanation:

DE: $\sqrt{90}$

^^ $\sqrt{(-1-8)^{2}+ (-3--6)^{2} }$

$\sqrt{-9^{2} +3^{2}$

$\sqrt{81+9}$

EF: $\sqrt{65}$

^^ $\sqrt{(-2+1)^{2} + (5+3)^{2} }$

$\sqrt{-1^{2}+8^{2}$

$\sqrt{1+64}$

DF= $\sqrt{101}$

Step-by-step explanation:

Building scale is 1cm=5feet

This means 1 cm is equivalent to 5 feet

If 1 cm is equals to 5 feet and the owner wants a 25% increase in dimension, this means;

25/100 =0.25.

0.25 x the actual dimension

0.25 x 5 = 1.25

1.25 + actual dimension

1.25 + 5 = 6.25.

This means the scale of the room will be on 1cm =6.25feet.

If the length of the room is A, the width is B;

The new length will then be 1.25 x A =1.25A

1.25A + A

The length of the new room is 1.25A +A

While the width of the new room is 1.25B +B
