Answer:

Step-by-step explanation:
<u><em>Using Pythagorean Theorem:</em></u>
=> 
Where c is hypotenuse, a is base and b is perpendicular and ( a, b = 4)
=> 
=> 
=> 
Taking sqrt on both sides
=> c = 5.7 units
Divide into shapes that you can find the area of.....
you also have to cross out the 5 and the 4s because you will not need them
2×2= 4 sq. cm
2×2= 4 sq. cm
9×2 = 18 sq. cm
18 + 4 + 4 = 26 sq. cm
so the area is 26 sq. cm
