Answer:

x = 7/ $\sqrt{2}$ or 4.949747468

Step-by-step explanation:

45-45-90 triangles have a specific pattern.

The smaller sides are x, & the hypotenuse is $x*\sqrt{2}$

With this knowledge, we know we have to divide the hypotenuse by $\sqrt{2}$ to get the smaller sides, so we divide 7 by the $\sqrt{2}$ to find x.

The area of a square piece of land is 784metersquared .What is the perimeter

Marta_Voda [28]

Answer:

112 m

Step-by-step explanation:

The area (A) of a square is

A = s² ( s is the length of side )

Here A = 784 , then

s² = 784 ( take the square root of both sides )

s = $\sqrt{784}$ = 28

Then

perimeter = 4s = 4 × 28 = 112 m
