Solve A=2(6.54*6.54+26.16*6.54+6.54*26.16)

$$A = 2 ( 6.54 \times 6.54 + 26.16 \times 6.54 + 6.54 \times 26.16 )$$

Solve for A

$$A=769.8888$$

Steps for Solving Linear Equation

Multiply 6.54 and 6.54 to get 42.7716.

$$A=2\left(42.7716+26.16\times 6.54+6.54\times 26.16\right)$$

Multiply 26.16 and 6.54 to get 171.0864.

$$A=2\left(42.7716+171.0864+6.54\times 26.16\right)$$

Add 42.7716 and 171.0864 to get 213.858.

$$A=2\left(213.858+6.54\times 26.16\right)$$

Multiply 6.54 and 26.16 to get 171.0864.

$$A=2\left(213.858+171.0864\right)$$

Add 213.858 and 171.0864 to get 384.9444.

$$A=2\times 384.9444$$

Multiply 2 and 384.9444 to get 769.8888.

$$A=769.8888$$

Assign A

$$A≔769.8888$$
