First I would find the base, which is a square so 10x10=100
then find the triangle (a=1/2bh) a=1/2(12)(10) a=1/2(120) a=60
since there are four triangle sides do 60x4 which equals 240, so then add the sides to the base 100+240=340, the answer is A
Answer:
<h3>1863 m squared</h3>
Step-by-step explanation:
So, the goal here is to find the area of each block individually then add it all together. In other words, you're gonna look for a way to solve for the missing square in the total large rectangle. Keep in mind 23 + 23 + 23 = 69 (aka the length of the whole rectangle)
So:
12 x 23 = the missing square = 276
31 x 69 = rectangle with the square = 2139
Total area = 2139 - 276 = 1863
Look it up :)))))))))))))
It means about 15 centimeters
