Answer:
114cm²
Step-by-step explanation:
Okay, so you can split this thingy up into a rectangle and another rectangle, so that's what we're going to do (see pic below)
So now we take off that 7 from the 13:
13 - 7 = 6
So now we find the area of that little area:
6 x 5 = 30
Now we do the other rectangle:
12 x 7 = 84
Now we add them together:
84 + 30 = 114
So the area of the shape is 114cm²
hope this helps:)
Answer:
4/9 and 1/64
Step-by-step explanation:
Do PEMDAS:
There are no parentheses or exponents, so move onto step 3 Multiplication
4/9 is the answer to the first problem
Again there are no parentheses or exponents, so move onto multiplication
1/64 is the answer to the second problem
