Step-by-step explanation:




Answer:
A = 57.97 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A =
h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 6.2, a = 10.8 and b = 7.9, thus
A =
× 6.2 × (10.8 + 7.9) = 3.1 × 18.7 = 57.97 cm²
I can’t see the data did you forget to put it or like forget to put a picture???
The opposite operation of squaring is to find the square root. I dunno what the original equation is so I can’t help with that
