Question

The area of square picture frame is 1600 cm^2 find the side length of the frame

Answer 1

Answer:

40 cm

Step-by-step explanation:

Given :-

• The area of a square frame is 1600cm²

And we need to find the length of side of the frame. We know that in a square all sides are equal. Therefore it's area is square of side . Using that we have ,

Using Area of Square's Formula :-

$:\implies$ Area = side²

$:\implies$ Side² = 1600 cm²

$:\implies$ Side = √[ 1600 cm²]

$:\implies$ Side = √[ 40cm * 40cm]

$:\implies$ Side = 40 cm .

Hence the measure of side of the frame is 40 cm .

Answer 2

Answer:

40cm.

Step-by-step explanation:

Given that the Area = 1600$cm^{2}$

Equation for Area of a square is $side^{2}$ (or side x side )

$side^{2}$ = 1600$cm^{2}$

side = $\sqrt{1600}$

side = 40cm.

Thus, the side length of the square frame would be 40cm.
