Answer:
0.35 meters^2 or 35 cm^2
Explanation:
we break up the shape and the problem into two parts.
we will begin by finding the area of the triangle first (or you could find the square's area first) and we know the area formula for a triangle is
Area (triangle) = (1/2) base x height
height = 0.04 meters or 4cm
base = 0.05 meters or 5 cm
therefore the area is:
(1/2) (5cm)(4cm) = 10 cm^2
now we find the area of the square which is very easy. it is simply base times the height (b x h)
Area (square) = 5cm x 5cm = 25cm^2
finally, we add the total area
Area (total) = Area (square) + Area (triangle) = 10 cm^2 + 25 cm^2
= 35 cm^2
