Answer:
area of arrow=610cm²
Step-by-step
First find the area of the square then the are of the triangle then add together to get the area of the arrow.
1.
Area=length x width
=20cm x 15cm
=300cm²
2.
Area= 1/2 base x height
=1/2 x 20 x 31
=1 x 10 x 31
=310cm²
(NOTE: TO FIND THE BASE YOU ADD THE 15CM FROM THE SQUARE AND THE 2 EIGHT'S FROM THE BOTTOM OF THE TRIANGLE)
3.
Total area or area of arrow
=300cm²+310cm²
=610cm²
Area = *Longer Side* x *Shorter side*
44 = (x + 7) * x
44 = x^2 + 7x
0 = x^2 + 7x - 44
0 = (x + 11)(x - 4)
0 = x + 11 OR 0 = x - 4
x = -11*impossible* OR x = 4
So x = 4
