cm and breadth is 3 cm.
3. Find the area of a square of side 11 m.
4. Find the area of a rectangle that is 14 m long and 5
m wide.
5. Find the perimeter of an equilateral triangle with
side 15 cm.

1. The volume is 729 V = 729  a Edge  9cm. V=a3=93=729cm3

2. perimeter =2(L+w)  length 4cm width positive

3. Area =121m2. a Side 11cm. A=a2 =112=121m2

4. A = length and width

5.  Perimeter =45 . a side 15cm. P=3 a=3.15=45cm

Step-by-step explanation:

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
