Please could someone help me understand this? thank you

here ..

length=6cm

breadth=4cm

height=5cm

we know that,

Total Surface Area of Cuboid, (S )= 2 (lb + bh + lh)

=2(6*4+4*5+6*5)

=2(24+20+30)

=2*74

=148

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
