Question

can you explain step by step how to solve this?

Answer 1

Remember that

the area of a parallelogram is equal to

A=b*h

in this problem

b=35 cm

h=44 cm

substitute

A=35*44

A=1,540 cm2

Find out the perimeter

P=2*(35)+2*(47)

P=164 cm

Problem N 2

we know that

the length of the wall is 170 inches

step 1

Find out the dimensions of the diagonal of the square

Applying the Pythagorean Theorem

d^2=12^2+12^2

d^2=2*12^2

$d=12\sqrt[\square]{2}\text{ in}$

Divide the length of the wall by the length of the diagonal

$\frac{170}{12\sqrt[\square]{2}}=10.02$

therefore

I need 11 (1/2 tiles)

Note I rounded up because with 10 (1/2 tiles) the length is less than 170 inches
