By substituting l with 10.8 and w with 8.3 in the expression 2l + 2w and performing the addition, we get the evaluated result of 38.2.
To evaluate the expression
2l+2w when l=10.8 and w=8.3, follow these steps:
Step 1: Substitute the given values of
l and w into the expression
2l+2w=2(10.8)+2(8.3)
Step 2: Perform the multiplications.
2(10.8) equals 21.6
2(8.3) equals 16.6.
Step 3: Add the results of the multiplications.
2l+2w=21.6+16.6
Step 4: Add the values together.
2l+2w=38.2
Therefore, when l=10.8 and w=8.3 the value of 2l+2w is 38.2. This calculation involves substituting the given values into the expression and then performing the required multiplications and additions to find the final result.
