When you see this kind of question use « BODMAS »
1.Add the 2 digits which is 3+7=10
2.Add the digits inside which is 0.7+1.3=2
3.Add the inside and outside
3+7(0.7+1.3)
10(2)=20
Answer:
Area is 70ft
Step-by-step explanation:
Area of a triangle is A=b × h/ 2 or A=1/2×bh
Let height equal h & base equal b
So,
h=14
b=10
Solve,
A=1/2×14×10
A=1/2×140
A=70
Therefore, the area is 70 feet
Ok so the solution which greenrune will (hopefully) correct
total is 1.5
p+r=1.5
rule is 1 more than pencil
r=1+p
sub 1+p for r
p+1+p=1.5
2p+1=1.5
minus 1 from both sides
2p=0.5
divide both sides by 2
p=0.25
pencil=$0.25
A =(b x h)/2
= 10 x 8
= 80/2
= 40 mm square
