Create rectangles by moving triangular pieces around:
Triangle A fits at location A', so you get a rectangle of 9*6 = 54 ft²
Triangle B fits at location B', so you get a rectangle of 5*4 = 20 ft²
totals to 20+54=74 ft²
Answer:
The equation is: and the number is 72.
Step-by-step explanation:
We have to use mathematical notation to convert the given statement into an equation. As we don't know the exact value of number, we have to use a variable in place of the number.
Let x be the required number then
"A number decreased by 7"
"and then divided by 5"
" is 13."
For solving, multiplying both sides of equation by "5"
Adding 7 on both sides of equation
Hence,
The equation is: and the number is 72.
