Answer:
Blue Rectangle: <u>135 mm²</u>
Blue Triangle: <u>45 mm²</u>
<em>Not sure if you need this but the </em>Total Square: <u>225 mm²</u>
Step-by-step explanation:
Area of a rectangle: <u>length x width</u>
Area of a triangle: 
<u> x base x height</u>
First find the area of the blue rectangle.
Length = 15 mm
Width = 9 mm
Area = 135 mm²
Now find the area of the blue triangle:
Base = 6 mm (because the bottom is 15 total and you subtract the 9)
Height = 15 mm
Area = 45 mm²
Hope it helps!

<span>Write the decimal number as a fraction
(over 1)
4.3 = 4.3 / 1
Multiplying by 1 to eliminate 1 decimal places
we multiply top and bottom by 1 10's
Numerator (N)
N = 4.3 × 10 = 43
Denominator (D)
D = 1 × 10 = 10
N / D = 43 / 10
Simplifying our fraction
= 43/10
= 43/10
= 4 3/10</span><span>
