The right answer is
D.)
Hope this helps :)
Answer:
Step-by-step explanation:
Area of polygon = area of square + area of triangle
Square:
Side = 12 cm
Area of square = side *side
= 12 * 12
= 144 sq.cm
Triangle:
base (b) = 12 cm
Height h = 19 cm

= 6 * 19
= 114 sq.cm
Area of polygon = 144 + 114 = 258 square cm
The prefix 'd' stands for "deci-", which is a multiplier of 1/10. This 1 dL is 1/10 of a liter. Hence
Multiply this equation by 6.88, and you get
Answer:
A = 99 cm²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
Here b = 18 and h = 11 , then
A =
× 18 × 11 = 9 × 11 = 99 cm²
