Answer:
57cm²
Step-by-step explanation:
area for trapezoid=
b¹+b²=x
x÷2=v
v×h=z
h=height
b=base
14+5=19
19÷2=9.5
9.5×6=57
Answer:
2√137
Step-by-step explanation:
To find AB, we can use the Pythagorean Theorem (a² + b² = c²). In this case, a = 22, b = 8 and we're solving for c, therefore:
22² + 8² = c²
484 + 64 = c²
548 = c²
c = ± √548 = ± 2√137
c = -2√137 is an extraneous solution because the length of a side of a triangle cannot be negative, therefore, the answer is 2√137.
