B refers to the base of the triangle,
and a signifies the length of the two identical sides.
The measurement labeled as 'a' is larger than 'b' since those equal sides are longer than the base. Given "one of the longer sides measures 6.3 cm," we assign a = 6.3.
Substitute 6.3 for each 'a' in the equation and solve for b:
2a + b = 15.7
2(6.3) + b = 15.7
12.6 + b = 15.7
b = 15.7 - 12.6 (applying subtraction property of equality)
b = 3.1
The result is calculated as 10 multiplied by 8 multiplied by 5, which equals 400.
Step-by-step explanation: We have the dimensions of a rectangular field given in feet. We are informed that an extension of

feet is made to each side. Therefore, the new dimensions can be calculated accordingly. Hence, they are presented as .
