252in^2

Step-by-step explanation:

area of whole square with no pieces missing = 21×15=315

in order to work out area, we now need to take away the area of the gaps

Gap 1)6×3=18in.^2

Gap 2)6×3=18in.^2

Gap 3)9×3=27in.^2

315-18-18-27=252in.^2

hope this helps :)

Hint: Split the figure into different sections.

Step-by-step explanation:

For example, say I split it to make it into three sections. It would be easier to visualize lines that cut the figure by drawing it out. The first is 3 inches and 6 inches. In order to find the area, all I have to do is multiply both of them, (6 x 3 = __). Then for the second section, let's make it 6 inches and 9 inches, which are at the bottom part of the figure. Again, you multiply both sides to get your area, (6 x 9 = __). The third section is a repeat of the previous sections, only now you multiply 15 inches and 12 inches. All that is left would be to add all the areas together to get the area of the entire figure.

(Tell me if you still need more clarification).
