I had this problem on my homework so, I can help.
1.Define the variable.
A=area (48)
B=base (12)
H= height ?
2. Then write the literal equation, which is:
2a/b=h
3.Plug in variable:
(2)48/12=h
(2)48=96
96/12=8
h=8
3. Check:
12x8=96
4. Write a sentence.
I hope this helped! : D
The area of triangle is : 18.0
Area of a triangle = 1/2 (Base x Height) Example: Width 13cm, Height 5cm, Base 12cm then; Area=1/2(12cm x 5cm) Area=6cm x 5cm Area=30cm2
60 sq cm
Area = 0.5*12*7 = 42 square cm
Base x Height / 2 So it's 12x8.5/2= 51
assuming its an isosceles triangle, then its 16 cm high
this is 5cm (:
The area is 108cm2
Area is 36cm2
The area of triangle is : 18.0
Area of a triangle = 1/2 (Base x Height) Example: Width 13cm, Height 5cm, Base 12cm then; Area=1/2(12cm x 5cm) Area=6cm x 5cm Area=30cm2
3.5
The area of a triangle = (base * height) / 2. So here, the area = 12 * 7 / 2 = 84/2 = 42 cm2.
Area of a triangle = 1/2 * Base * Height = 1/2 * 12 * 6.5 = 39 cm2
=48
60 sq cm
The area of a 12cm by 5cm right-angled triangle is: 42 cm2
