Answer:
A) 95m²
Step-by-step explanation:
Since the garden is in the shape of a triangle, use the formula for area of a triangle. A = bh/2 or A = 1/2 bh
"A" is for area.
"b" is for base.
"h" is for height.
The area of a triangle is base times height divided by two or half times base times height. Dividing by 2 and multiplying by 1/2 are the same.
The base of the garden is 19m and the height is 10m. The height is always perpendicular (90°) to the base and meet the vertex opposite to the base.
b = 19m
h = 10m
Substitute (replace) the variables in the formula with the values.
A = bh/2
A = (19m)(10m)/2 Multiply 19m and 10m. Don't forget to multiply the units.
A = (190m²)/2 Divide by 2.
A = 95m² Area of garden
When you multiply numbers with units, multiply the numbers, then multiply the units. Add the exponents for the units. The exponent for meters is 1, and 1 + 1 = 2. (m X m = m²)
Therefore, the area of the garden is 95 square meters.
