Answer:
254.44cm²
Step-by-step explanation:
For the triangles do pythagoras theorem:
a²+b²=c²
c=hyptonuse=8.8
b=6.2
so we don't know what a is.
We rearrange a²+b²=c² to get a²=c²-b²
8.8²=77.44
6.2²=38.44
77.44-38.44=39
square root of 39 is 6.2(1 d.p)
a=6.2
6.2x6.2=38.44cm²
6.2x7.2=44.64cm²x2=89.28cm²
8.8x7.2=63.36cm²x2=126.72cm²
126.72+89.28+38.44=254.44cm²
2340÷100= 23.4 , but you can't have a part of a box, so 24 is the answer
First you calculate the area of the triangle:
square yards.
For the base and the height of the triangle you need to count how many squares it takes on the picture.
For the rectangle you need to calculate the length and the height first.
For each we are going to use the Pythagorean theorem:
yards
Again count the numbers of squares for the triangle in which the rectangle's height is the hypotenuse.
We do the same for the Length of the rectangle:
yards
Now we calculate the area of the rectangle:
square yards.
The total material area to cover both is:
3 + 26 = 29 square yards
