Answer:
247 yd²
Step-by-step explanation:
this figure can be "split" into 3 sub-figures.
2 rectangles and one triangle "at the top".
these 3 areas can be easily calculated, and the we simply sum them all up, and that is the total area.
my approach is to pick the first rectangle to be the one extruding one to the right.
R1 = 11×5 = 55 yd²
the second rectangle is then the rest of the"straight" area up to the beginning of the triangle top
R2 = 8 × (13+5) = 8×18 = 144 yd²
and the area of a triangle is
baseline × height / 2
we can clearly see in our example, it is a right-angled triangle, so the left side is also the height, which is the remainder of the long side of the original figure, when we deduct all the other parts we used for the rectangles.
so, we have
T = 8 × (30 - 5 - 13) / 2 = 8×12/2 = 8×6 = 48 yd²
so, in total we have
F = 55 + 144 + 48 = 247 yd²
Answer:
Step-by-step explanation:
find the prime factors of given numbers:
126= 2*3*3*7- this side can be cut into any number here or combination of numbers as per factors
108= 2*2*3*3*3 - same as above
As per prime factors, the squares can be of sizes:
2×2, 3×3, 6×6, 9×9 and 18×18
The least number can be obtained with the biggest size option 18×18, this will give 7*6=42 square
