Use the diagram and the Pythagorean Theorem to find the EXACT area of square ABCD
Burka [1]
ANSWER

The area of square ABCD is
25 \: square \: unit

EXPLANATION

The area of square ABCD is the square of the length of one side.

That is the area of ABCD is |AD|²

From Pythagoras theorem,

{|AD|}^{2} = { |AG| }^{2} + { |GD| }^{2}

We can read from the graph that, each box is one unit.

This implies that,

{|AD|}^{2} = {4}^{2} + {3}^{2}


{|AD|}^{2} =16 + 9

{|AD|}^{2} =25

Therefore the area of square ABCD is 25 square units.

The correct answer is option C.
